EMPI Main Jet .125 for DGV, DFV, ICT, and EPC Carburetors
Product Overview
The EMPI .125 Main Jet is a precision-engineered component designed for fine-tuning the fuel delivery in your Weber-style carburetor. Whether you are running a progressive DGV on a street Beetle or dual ICTs on a performance engine, having the correct main jet size is essential for achieving the perfect air-fuel ratio at cruising and high speeds. These jets are manufactured to exacting standards to ensure consistent fuel flow and engine reliability.
VW Fitment & Application
This main jet is compatible with a wide range of popular Volkswagen aircooled carburetor setups, including the Weber DGV, DFV, and ICT series, as well as the EMPI EPC versions. These carburetors are frequently found on VW Beetles, Karmann Ghias, Type 2 Buses, and custom Dune Buggies or Sand Rails. Because engine displacement, camshaft profiles, and exhaust systems vary, these jets are sold individually to allow for specific calibration tailored to your unique VW engine build.
Pro Tech Tips for Carburetor Tuning
Read Your Plugs: After installing the .125 main jet, perform a "plug chop" by running the engine at sustained high RPMs and then shutting it off immediately. Inspect the spark plug porcelain; a light tan color indicates the jetting is correct, while a white appearance suggests a lean condition requiring a larger jet.
Altitude Adjustments: If you frequently drive your VW from sea level to higher elevations, remember that higher altitudes generally require smaller main jets due to the thinner air. If your engine feels sluggish or "bogs" at high altitudes, you may need to step down from the .125 size to maintain a crisp throttle response.
Use the Right Tools: These brass jets are precision parts and can be easily damaged. Always use a flat-head screwdriver that fits the jet slot perfectly and snugly. Using an undersized screwdriver can burr the brass or distort the orifice, which will negatively impact your fuel metering and engine performance.
